the first person forgot the +7, the answer is x=9/2

x - 4(x - 3) + 7 = 6 - (x - 4)
The first step would be to remove the parentheses by distributing the number outside. In the first set of parentheses, the -4 is being distributed; in the second set, just the minus sign (which is in actuality -1).
x - 4x + 12 + 7 = 6 - x + 4
Now, group like terms,
-3x + 19 = 2 - x
Move all x terms to the left hand side, all numbers to the right hand side,
-3x + x = 2 - 19
Now, group like terms again,
-2x = -17
Divide both sides by -2,
x = 17/2

Solving for x:
x-4(x-3)+7 = 6-(x-4)
x-4x+12+7 = 6-x+4
-3x+19 = -x +10
2x = 9
x = 4.5

x-4x+12+7=6-x+4
-3x+19=10-x
+x +x
-2x+19=10
-19 -19
-2x=-9
x= -9/-2
x=4.5

+x
2x -4x +12 = 6+4
-2x +12 = 10
-12
-2x = -2
/-2
x=1

x^2 - 4x - 3x +12 +7 = 10 - x
x^2 - 7x +19 = 10 - x
x^2 - 6x + 9
(x - 3)(x-3)

x= -1/3(-9-x)? I might have expanded it wrong though
